Hair waving pad



INVENTOR ATTORNEYS May 2, 1933. E; s. McDONOUGH HAIR WAVING PAD Filed Jan. 4, 1933 Patented May 2, 1933 UNITED STATES PATENT OFFICE EVERETT G. MCDONOUGH, OF MOUNT VERNON, NEW YORK, ASSIGNOR T ZOTOS CORPORATION, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK HAIR wavme ran Application filed January 4, 1933. Serial No. 650,079.

This invention relates to certain improvements in hair waving pads for use where a pro-formed tress of hair is subjected to the action of an exothermic material contained within the pad, which exothermic material when moistened will, of itself, generate heat suflicient to impart a so-called permanent wave to the pre-formed tress.

My improved hair waving pad compr ses an outer wrapper, an envelope contammg an exothermic material and having a perforated face, a removable sealing sheet adhered to the perforated face of the envelope for sealing its perforations, an absorbent sheet adapted to be placed upon the perforated face of the envelop after the sealing sheet has been stripped therefrom, and an inner flap adapted to be folded over onto the moistened sheet.

The object of my invention is to produce a hair waving pad of the above character in which the step of perforating the envelope containing the exothermic material immediately before the application of moisture thereto, is eliminated, thus permitting the pad to be shipped vwith the face of the envelope already perforated and temporarily sealed.

Practical embodiments of my invention 39 re represented in the accompanying drawing, in which:

Fi 1 re resents an inside plan view of one orm o pad;

Fig. 2 represents a similar view of another form of pad;

Fig. 3 represents a similar View of a third form of pad; and

Fig. 4 represents a similar view of a fourth form of pad.

The outer wrapper 1 of the pad is shown as comprising a once folded sheet of impervious material, such for instance as parchment paper, foil, or the like.

The envelope 2 which contains the exothermic material 3, such. for instance as calcium oxid in powdered form, has its face perforated as shown at 4. This envelope is also of impervious material, such for instance as foil.

A removable sheet 5 of impervious nonsoluble material, as foil, is placed upon and adhered to the perforated face of the envelope 2 for sealing the perforations 4. The sealin adhesive may be of some suitable material, such for instance as petroleum jelly, which will not injuriously afiect the pre-formed hair tress or the exothermic action of the material within the envelope, when the pad is in use.

A sheet 6' of absorbent material is shown as a flap projecting from the pad in position to be moistened and then folded over onto the perforated face of the envelope 2 after the loose sealing sheet 5 has been stripped from the perforated face of the envelope.

A sheet 7 of impervious material, such for instance as foil, is interposed between the envelope 2 and the outer wrapper 1, which sheet is shown as extended to produce 7 a foldably flap 8 adapted to be folded over onto the moistened absorbent flap 6 after the flap has been folded over onto the perforated face of the envelope.

In the forms shown in Figs. 1 and 3, the 7 flap 8 is perforated to permit a more direct action of the heat upon the pre-formed tress when the pad is applied thereto, the perforation in the said sheet being denoted by 9. In the forms shown in Figs. 2 and 4, this flap 8 is unperforated to cause a less direct heat action upon the pre-formed tress.

In practice, the pre-formed tress of hair, not shown herein, may be moistened, either before or after it is wound, with a suitable hair waving solution. The loose sealing sheet 5 is stripped from the perforated face of the envelope containing the exothermic material. The absorbent flap 6 is moistened and folded over onto the perforated face of the envelope. The inner flap 8 of the sheet 7 is then folded over onto the moistened flap 6.

In some instances where a less direct heat action on the pre-formed tress is desired, the removable sealing sheet 5 may either be placed on the moistened sheet 6 or wrapped around the pre-formed tress before the pad is applied. The pad is then wrapped around they pre-formed tress in the usual manner and the exothermic action starts at once.

Heat is thus set up within the pad sufficient to impart a so-called permanent wave to the pre-formed tress without requiring application of heat from an outside source.

It will be seenthat in the forms shown in Figs. 1 and :3, the removable sealing sheet 5 projects beyond the end of the inner flap -8, thus permitting the sealing sheet when 'said removable sheet is stripped from the perforated face of the envelope.

From the above descri tion it will be seen that by sealing the per orated faces of the envelopes containing the exothermic material, the pads may be shipped in quantities and the exothermic material protected from deterioration by exposure to varying atmospheric conditions until the time comes for using the pads.
